Application filed September 2, 1908'. Serial No. 461,417.

To all whom it may concern: 7

Be it known that 1', JOHN H. OWEN, a citizen of the United States,residing at Stuttgart, in the county of Arkansas and State of Arkansas,have invented certain new and useful Improvements in Pumps, of which thefollow' 1s a specification.

This lnvention comprehends certain new and useful improvements in liftpumps of that t which operate on the centrifugal princip e, and theobject of the invention is animproved machine of this character, theparts of which are so arranged and braced as to render the pumpsusceptible of being swung into position in a pit, or lake, orthe like,without sustaining any injury, and

which embodies improved means for eflectuall raising the water and alsoreducing the riction of the same within the casing, thereb increasingthe efficiency of the pump and e ecting a material economy in the powerre uired to operate the same.

Vith this and other objects in view that will more fully appear as thedescription proceeds, the inventlon consists of certain constructions,arrangements and combinations of the parts that I shall hereinafterfully describe and then point out the novel features thereof in the apended claim.

For a full un erstanding of the invention, reference is to be had to thefollowing description and accompanying drawings, in which:

Figure 1 is a vertical section of a pump constructed in accordance withmy invention; Fig. 2 is a top plan view of the wheel with the innermember removed, and Fig. 3 is a transverse section.

Corresponding and like parts are referred to in the followin descriptionand indicated in all the views 0 the drawings by the same referencecharacters.

Referring .to the drawing, the numeral 1 designates a substantiallyvertically disposed tubular pump casing that is preferably constructedin a plurality of sections 2 formed at their ends with outstandingannular flanges, by means of which the sections are detachably coupledtogether by bolts or other suitable fastening means. Thelowermostsection 2 constitutes an intake and is designed to be submergedin the water to be raised and to conduct the same to an enlargement 4formed intermediate of the ends of thecasing and having its lowerportion preferably hollow and semi-spherical in form,

while its upper portion tapers upwardly to the ordinary diameter of thepump casing, as shown. The uppermost section 2 has 0. lateral tubularprojection constituting a discharge pi e or spout 5, and is provided atits u per on with a centrally perforated head 6 w rich is formed aroundthe perforation with an upwardly disposed hollow boss 7 in which fitsthe upper end of a longitudinal pipe 8. The extremity of this pipe 8 isenlarged'as shown, so as to rest upon the u per ed e of the boss and besustained there y, sai enlarged portion of the pipe being also designedto accommodate a run-way 9 having a plurality of antifriction balls 10upon which rests a relatively stationary collar 11 secured on a verticalpum shaft 12 so as to suspend the same within t e pipe 8 and render itsusce tible of rotation therein.

igidly secured upon the upper extremity of the shaft 12 above the collar11 is a alloy 13 around which extends a drive belt 14 that is designedtotransmit motion to the pulley from an en ine or other suitable source ofower not s own. In order to increase the ictional contact of the drivebelt with the pulley, I preferably provide an idler or belt tightener15, the s indle 16 of which is journaled in a prefera ly brass bearing17 that is secured Within a box or casting 18 by means of a set screw orthe like, said box being supported upon an outstanding arm 19 carried atthe upper end of the pump casing 1.

The shaft 12 and the pi e 8 in which it is revolubly mounted, extentdownwardly into thepump casing 1 and are preferably constructed in twoor more sections that are suitably coupled together, the pipe 8 beingpreferably sustained centrally within the pump casing by means ofaspider 20. The owermost section of thepipe 8 terminates in the upperportion of the enlargement 4 of the casing and fits within alongitudinally disposed sleeve 21 that is supported therein by means ofa plurality of braces 22, the pipe being formed at its extremity with anoutstanding flange 23 adapted to abut against the adjacent end of thesleeve and the pipe is provided in proximity to the other end of thesame with a coupling collar 24.- whereby to hold the pipe against anylongitudinal and which in the present instance is coneffect theelevation of the water in the casing relation thereto, as shown. Theinner mom ber25 is keyed or otherwise secured upon the shaft in anyapproved manner, so as to rotate therewith, and the outer member 26 issupported from the inner member through the instrumentality of alurality of blades 27 which are interposed between the members andpreferably have a s iral arrangement as best seen in Figs. 1 an 2, andwhich divide the space between the sections into a plurality of windingwater ways that lead from a central aperture 28 extending through theouter member 26 in registry with the intake 3, to the upper end of thewater wheel.

From the foregoing description in connection with the accompanyingdrawing, it will be apparent that as motion is transmitted to the pulley13 by means of the drive belt 14, the rotation of the shaft 12 and thewater wheel attached thereto, will be effected. As the water wheelturns, the air in the winding water ways is thrown outwardly andupwardly by centrifugal .force and a vacuum is thus created in' thespace between the'members 25 and 26, whereby to cause a suction throu hthe intake 3 and draw the water upwardly through the same into theenlargement 4 of the casing. The Water as it thus flows into the windingwater ways of the wheel, is discharged therefrom by means of thecentrifu a1 action and is forced u wardly through t e pump casing 1 anddisc arged through the pipe or spout 5, the water continuing to beraised as the pump remains in operation. It is to be particularlyobserved, however, that as the water leaves the water ways at the upperend of the wheel, the outward and upward twist that it receivestherefrom, causes it to flow the present instance, in order to furtherreduce the friction within the pump, I preferably provide an oil cup 29which issu ported in any suitable manner from t e pump head 6 above theantifriction bearin 10 and which is designed to conduct the oi to saidbearing by means of a feed pi e 30 which extends downwardly below theower end of the pulley and then upwardly between the same andthe hollowboss 7, the oil overflowing from the antifriction bearing and passingdownbetween the shaft 12 and the pipe 8 in which the same is journaled,so as to effect the lubrication of said journal and thus substantiallyall of the movable parts of the machine. Attention is directed to thefact that the lower end of the belt idler 15 is formed with anoutstanding annular flange serving to keep the belt and pulley fromdropping down.

Having thus described the invention, what is claimed as new is:

A centrifugal pum of the character described, comprising a ollow casingprovided atits opposite ends with an intake and a discharge outlet andformed intermediate of its ends with a lateral enlargement, the upperand lower portions of the enlargement tapering op ositely, alongitudinal shaft journaled wit 1in the casing and extending into theenlargement, and a transversely disposed water wheel rigidly mountedupon the shaft and arranged entirely within the lower portion of theenlargement and' designed for rotation therein, said water wheelconsisting of inner and outer members tapering similarly to the lowerportion of the enlargement, the outer member substantially incasing theinner'member in spaced relation thereto and being formed with a centralaperture in registry with the intake, and a plurality of s irallyarrangedblades interposed between t e members and ri idly securedthereto and dividing the space etween the same into a plurality ofwinding waterways leading from the central aperture and adapted to dis'charge water against the upper tapered portion of the enlargement.

In testimony whereof'I afiix my signature in presence of two witnesses.
